IF'ASTENlNG FOM MASSIVE TIRES.

SPECIFICATION forming part of Letters Patent No. 777,314, dated December 13, 1904.

Application filed June 8, 1904;. Serial No. 211,643. (No model.)

T cir/ZZ whom t 711/003./ concern.'

Be it known that INVILHELM STRUGK, a citi- Zen of the free town oi? Hamburg, and a resident or' l2 Illstrasse, Friedenau, near Berlin,

Germany, have invented certain new and useful lmprovements in the Fastening oil Massive Tires, oi which the following is a specilication.

The method of Xing rubber tires to the wheels ot' vehicles by means of removable lat- 1o eral rings provided with radial projections by means of which they enter slots in the telly or rim is known, and it is also not novel to provide a solid rubber tire with an inner metal core or layer for limiting its expansion.

I5 rllhe present invention refers to improvements relating to solid rubber tires; and it consists in making the metal core or layer to project from the tire and providing it with a head or the like, so that when mounting' the 2o tire on the telly all the force can be directly exerted on said core or layer.

In the annexed drawings part oit' a tire oi? this kind is shown in Figures l and 2 in side view and plan, respectively, and in Fig. 3 in cross-section.

a is the rubber tire, l the metal core or layer, and e is the head of said core projecting from the tire. is the metal telly or rim, and b is the wooden telly, 0i the wheel when 3o the latter is required.

As shown in Fig. 2, the edge of rim '1f can be either cut away in wedge form, as at on., or projections f: on the iiXing-ring Acan be formed as wedges.

The metal rim e' is provided with an annular grooveffor reception ol the head e and the fixing-ring Z. The edge g of the rim e' projects above said groove f only so 'far that the head e of the metal core lying against the rim may pass over said edge (7. rlhis edge is 40 also provided with recesses 7i. and the ring l with inwardly-directed projections (shown in Fig. 1 in dotted lines,) said projections being of the same or slightly less length than the recess/1., so that the ring Z is connected bayonet fashion to the rim.

When the projections ci the ring lare passed through the recesses /t in the annular groove 7 of the rim and the ring is then turned, 'for instance, in the direction indicated 50 by the arrow n., Fig. 1, it bears against the head a and presses the tire into the rim e', the wedgc-lilce reduction of the edge (y or of the projections facilitating the introduction of the ring Z and eii'ecting a strong pressure of 55 the tire on the rim.

It is preferable that the rubber be harder adjacent the metal core or layer Z than at the other parts.

Owing to the above arrangement, the tire and rim need only correspond as regards diamcters, no restrictions as to width being necessary.

1V hat I claim as my invention, and desire to secure by United States Letters Patent, is 65 The combination, in a fastening for massive tires on wheel-fellies, with a metal mounting' Z in the massive tire a of a projection c on one et' its sides, said projection fitting in a groove formed by the telly I and the telly-ring l, sub- 70 stantially as and i'or the purpose set iorth.

The foregoing specification signed at Berlin, Germany, this 12th day of December, 1903.
